Nicholls Boreholes were contacted by Agrivert, a sustainable and cost-effective organic waste management solutions company, to drill and install a 250 metre deep water borehole to supply their £11 million anaerobic digestion (AD) plant in Chertsey, Surrey.

As a specialist borehole drilling company we are experienced in supplying, fitting and maintaining commercial water or waterwell boreholes for a wide range of commercial customers and our experience means we can use precisely the right equipment for any geology, which in this particular case was a clay based strata.

Commercial-water-borehole-drillingWith our own drilling equipment it was necessary to drill to the depth of 250 metres to extract water from the chalk aquifer. The water borehole was steel lined to 178 metres to avoid unwanted water ingress from the clay. We then installed a pump (to raise the water to ground level) and then fitted it with a cover to protect the ground water supply from pollution.

Agrivert wanted their own private water supply to mix with the food waste which generates a bio gas. This bio gas is then burnt in a turbine to generate electricity which is exported into the national grid. This commercial water borehole (waterwell) will, in the long term save Agrivert money, provide a cleaner, ‘greener’ source of water and also added value to their site.
